My composition turns black before timeline ends.

[rocior81320390]

Hi,

I'm working on a project that's supposed to be 15 seconds long. But I noticed my composition is turning all black before those 15 seconds are up. It happens around the 14th second or so, so there's a whole second of all-black screen, which I don't want.

On the first picture you can see, this is the last moment in which I can see the comp. But you can also see it's supposed to last beyond that.

This is the first instance in which the all black screen problem starts. There's still a couple seconds to go before the 15 seconds are actually up.

I've never had this problem before, and it looks as if everything's set up correctly... is there something I'm missing?

I'm using After Effects 23.4.0.

Thank you.

You need to dig into the nested comp in the timeline. The Comp Flowchart would be a good place to start.

I checked every nested comp and layer and found no problem, but just in case I set them all to the duration of 16 seconds and then made a Premiere project of 15 seconds and exported from there. Not super sure what the issue was, but this was the workaround.
